Thank you.  Live and learn.  

You betcha!

Ive had it prompt me to attach for certain states, but not all of them, I do what the software tells me to, if it doesnt insist that a copy be attached, I dont attach it, never had a letter requesting one that hadnt been attached.

It's an automatic prompt with Minnesota.  I don't do a lot of out of state client returns that require filing non-resident returns, but when I have I also needed to attach the non-resident returns.  So I only report on what I see.  It will be interesting next year if I pick up a couple of clients living in the new states of Greenland and Canada on what the requirements are.

I prepare Indiana, Michigan and Illinois.   I've never attached other state as PDF.    If the program prints the required attachments when printing filing copy, then it should be sent when e-filing.
